Description

La présente invention concerne un système électrique comportant, d'une part, un appareillage électrique à rapporter en saillie sur une paroi support le long d'une goulotte de cheminement de conducteurs électriques, et, d'autre part, un connecteur électrique pour le raccordement électrique d'au moins un conducteur électrique audit appareillage électrique.The present invention relates to an electrical system comprising, of a on the other hand, electrical equipment to project over a support wall along of a duct for conducting electrical conductors, and, secondly, a electrical connector for the electrical connection of at least one conductor electric to electrical equipment

Généralement, dans un tel système électrique, ledit appareillage électrique comprend une partie avant fonctionnelle et une partie arrière, à fixer sur ladite paroi, comprenant une ouverture latérale pour le raccordement de ladite partie arrière à l'espace intérieur du socle de ladite goulotte.Generally, in such an electrical system, said electrical equipment includes a functional front part and a rear part to be attached to the said wall, comprising a lateral opening for connecting said part back to the interior space of the base of said chute.

Un tel système d'appareillage électrique est généralement utilisé dans le cas d'une rénovation d'habitat.Such a system of electrical equipment is generally used in the case of a home renovation.

En effet, dans ce cas il est accouplé à différents types de goulottes (moulure ou plinthe) qui véhiculent des câbles ou conducteurs électriques, ce qui permet d'éviter de réaliser, dans les parois, des saignées pour des tubes pour conducteurs électriques et d'encastrer des boítes pour appareillages électriques.Indeed, in this case it is coupled to different types of chutes (molding or baseboard) which convey cables or electrical conductors, which avoids to make, in the walls, bleeds for tubes for electrical conductors and recess boxes for electrical equipment.

Toutefois, dans les systèmes électriques du type précité déjà connus, il est fréquent que certaines des bornes de connexion électrique du mécanisme d'appareillage électrique soient positionnées sur le dessus dudit mécanisme, ce qui oblige l'installateur à prévoir une longueur maximum de conducteurs électriques pour atteindre une telle borne. Cela n'est pas toujours aisé lorsqu'on rajoute un tel appareillage électrique sur un circuit déjà existant.However, in the electrical systems of the aforementioned type already known, it is common as some of the electrical connection terminals of the mechanism of electrical equipment are positioned on the top of the mechanism, which requires the installer to provide a maximum length of electrical conductors to reach such a terminal. This is not always easy when adding such electrical equipment on an already existing circuit.

Sur les figures 1 et 5, on a représenté un système électrique qui comporte un appareillage électrique 100 à rapporter en saillie sur une paroi support le long d'une goulotte 10 de cheminement de conducteurs électriques.FIGS. 1 and 5 show an electrical system which includes electrical equipment 100 to project over a wall support along a trough 10 for routing electrical conductors.

Ici, l'appareillage électrique 100 est un socle d'une double prise de courant fort femelle à la norme française.Here, the electrical equipment 100 is a base of a double plug of strong female current to the French standard.

Cet appareillage électrique 100 comporte une partie avant 110 fonctionnelle, représentée plus particulièrement sur la figure 7, qui est un capot parallélépipédique rectangle dont la face avant A est pourvue de deux puits 111 identiques, chaque puits 111 étant destiné à accueillir une fiche de prise de courant (non représentée) et comportant, dans son fond 112, des ouvertures circulaires 113 dans lesquelles sont destinées à s'insérer les broches de connexion d'une telle fiche pour être raccordées électriquement au mécanisme d'appareillage correspondant. This electrical apparatus 100 has a front portion 110 functional, shown more particularly in Figure 7, which is a hood parallelepiped rectangle whose front face A is provided with two wells 111 identical, each well 111 being intended to receive a plug of current (not shown) and having, in its bottom 112, openings in which are intended to insert the pins of connection of such a plug to be electrically connected to the mechanism corresponding apparatus.

Le fond 112 de chaque puits 111 de la partie avant 110 fonctionnelle de l'appareillage électrique 100 comporte, en outre, une ouverture centrale 114 dans laquelle est destinée à s'insérer une vis (non représentée) pour la fixation de la partie avant fonctionnelle à une partie arrière 120 de l'appareillage électrique 100.The bottom 112 of each well 111 of the functional front portion 110 of the electrical apparatus 100 further comprises a central opening 114 in which is intended to insert a screw (not shown) for fixing from the functional front portion to a rear portion 120 of the apparatus electrical 100.

Au surplus, le fond 112 de chaque puits 111 de la partie avant 110 fonctionnelle comporte une ouverture 115 permettant le passage d'une broche de raccordement à la terre 125A faisant saillie de la partie arrière 120 de l'appareillage électrique 100.In addition, the bottom 112 of each well 111 of the front portion 110 functional comprises an opening 115 allowing the passage of a pin 125A ground connection protruding from the rear portion 120 of the electrical equipment 100.

La partie avant 110 fonctionnelle comporte ici, sur un côté longitudinal, un auvent 116 destiné à venir recouvrir localement le socle 11 de la goulotte 10 le long de laquelle est rapporté l'appareillage électrique 100.The functional front portion 110 comprises here, on a longitudinal side, an awning 116 intended to cover locally the base 11 of the chute 10 along which electrical equipment 100 is attached.

Ici, l'auvent 116 vient de formation avec le capot parallélépipédique, mais il peut être rapporté sur celui-ci.Here, the awning 116 comes from formation with the parallelepipedic cover, but it can be reported on this one.

La partie arrière 120 de l'appareillage électrique 100 comporte un boítier isolant de forme parallélépipédique rectangle, globalement similaire à celle de la partie avant 110, pour constituer avec celle-ci un ensemble.The rear part 120 of the electrical equipment 100 comprises a housing rectangular parallelepiped-shaped insulation, broadly similar to that of the front part 110, to constitute with it an assembly.

Cette partie arrière 120 est destinée à être fixée sur la paroi support le long du socle 11 de la goulotte 10.This rear portion 120 is intended to be fixed on the support wall on along the base 11 of the chute 10.

A cet effet, le fond 121 du boítier isolant comporte, à ses quatre coins, des ouvertures 124 de forme oblongue destinées à être traversées par des organes de fixation à ancrer dans la paroi support.For this purpose, the bottom 121 of the insulating housing comprises, at its four corners, openings 124 of oblong shape to be traversed by fasteners to be anchored in the support wall.

Le fond 121 du boítier isolant de la partie arrière 120 de l'appareillage électrique 100 est bordé sur trois côtés par une paroi périphérique 122. Le quatrième côté, ici un côté longitudinal du boítier isolant, est ouvert de sorte que cette partie arrière 120 comporte une ouverture latérale 123 pour le raccordement de celle-ci à l'espace intérieur du socle 11 de ladite goulotte 10.The bottom 121 of the insulating housing of the rear part 120 of the apparatus electrical 100 is bordered on three sides by a peripheral wall 122. The fourth side, here a longitudinal side of the insulating housing, is open so that this rear portion 120 has a lateral opening 123 for the connecting it to the interior space of the base 11 of said chute 10.

Le boítier isolant de la partie arrière 120 de l'appareillage électrique 100 renferme deux mécanismes de prise de courant 125 identiques et reliés électriquement entre eux par des barrettes électriques, appelées "shunts", non visibles sur les figures.The insulating housing of the rear part 120 of the electrical equipment 100 contains two identical and connected 125 socket outlets electrically with each other by means of electric bars, called "shunts", no visible in the figures.

Les mécanismes de prise de courant 125 étant bien connus en eux-mêmes, ils ne seront pas décrits dans le détail. The socket mechanisms 125 are well known in themselves, they will not be described in detail.

Pour l'essentiel, ils contiennent chacun des bornes de raccordement électrique 125C, une borne de phase et une borne de neutre, dans lesquelles sont destinées à s'enficher les broches d'une fiche de prise de courant correspondante.Essentially, they each contain connection terminals 125C, a phase terminal and a neutral terminal, in which are intended to plug the pins of a socket plug corresponding.

Ils comprennent également chacun une broche de raccordement à la terre 125A, et, entre les deux ouvertures d'accès aux bornes de raccordement électrique de phase et de neutre, une ouverture 125B pour la fixation de la partie avant 110 fonctionnelle de l'appareillage électrique 100 via une vis traversant l'ouverture centrale 114 prévue dans le fond de chaque puits 111.They also each include a connection pin to the earth 125A, and between the two access openings to the connection terminals Electrical phase and neutral, an opening 125B for fixing the part before 110 functional of electrical equipment 100 via a through screw the central opening 114 provided in the bottom of each well 111.

Le boítier isolant de la partie arrière 120 de l'appareillage électrique 100 loge des lames métalliques de connexion électrique 126A, 126B, 126C, qui sont issues des mécanismes de prise de courant 125, et qui s'étendent selon un axe Y perpendiculaire à l'axe longitudinal X de la goulotte 10 en direction de ladite ouverture latérale 123.The insulating housing of the rear part 120 of the electrical equipment 100 houses electrical connection blades 126A, 126B, 126C, which are from the socket mechanisms 125, and which extend along an axis Y perpendicular to the longitudinal axis X of the chute 10 towards said lateral opening 123.

Plus particulièrement, les deux premières lames métalliques de connexion électrique 126A, 126B sont des lames de neutre et de terre. Elles sont issues d'un des deux mécanismes de prise de courant 125. La troisième lame métallique de connexion électrique 126C est une lame de phase et est issue de l'autre mécanisme de prise de courant 125.More particularly, the first two metal blades of electrical connection 126A, 126B are neutral and earth blades. They come from one of the two plug-in mechanisms 125. The third 126C electrical connection metal blade is a live blade and is from the other socket mechanism 125.

Le système électrique représenté sur les figures comporte, en outre, un connecteur électrique 200 pour le raccordement électrique d'au moins un conducteur électrique 1, 2, 3 aux mécanismes de prise de courant 125 de l'appareillage électrique 100.The electrical system shown in the figures further comprises a electrical connector 200 for the electrical connection of at least one electrical conductor 1, 2, 3 to the socket mechanisms 125 of the electrical equipment 100.

Ici, le connecteur électrique 200 permet le raccordement des trois lames métalliques de connexion électrique 126A, 126B, 126C issues des mécanismes de prise de courant 125 à trois conducteurs électriques 1, 2, 3 circulant dans le socle 11 de la goulotte 10.Here, the electrical connector 200 allows the connection of the three blades 126A, 126B, 126C electrical connection socket outlet 125 with three electrical conductors 1, 2, 3 flowing in the base 11 of the chute 10.

Ce connecteur électrique 200, plus particulièrement représenté sur les figures 2 à 4, comprend une cassette isolante 210, 220 à rapporter dans ladite ouverture latérale 123 de la partie arrière 120 de l'appareillage électrique 100 (voir figure 5), au-dessus du socle 11 de la goulotte 10.This electrical connector 200, more particularly represented on the Figures 2 to 4, includes an insulating cassette 210, 220 to report in said lateral opening 123 of the rear part 120 of the electrical equipment 100 (see Figure 5), above the base 11 of the chute 10.

A cet effet, il est prévu, sur le fond 121 du boítier isolant de la partie arrière 120 de l'appareillage électrique 100, un socle 127 dont la surface supérieure 127A reçoit la cassette isolante 210, 220 de sorte qu'elle se trouve positionnée dans ladite ouverture latérale 123, juste au-dessus des retours 14 des ailes latérales 12, 13 du socle 11 de la goulotte 10.For this purpose, it is provided on the bottom 121 of the insulating housing of the party rear 120 of the electrical equipment 100, a base 127 whose surface upper 127A receives the insulating cassette 210, 220 so that it is located positioned in said side opening 123, just above the returns 14 lateral wings 12, 13 of the base 11 of the chute 10.

Les lames métalliques de connexion électrique 126A, 126B, 126C, issues des mécanismes de prise de courant 125 logés dans le boítier isolant de la partie arrière 120 de l'appareillage électrique 100, s'étendent, selon la direction Y, juste au-dessus de la surface supérieure 127A du socle 127 prévu sur le fond 121 du boítier isolant.The electrical connection blades 126A, 126B, 126C, from the socket mechanisms 125 housed in the insulating housing of the rear part 120 of the electrical equipment 100, extend, according to the direction Y, just above the upper surface 127A of the base 127 provided on the bottom 121 of the insulating housing.

Avantageusement, cette cassette isolante 210, 220 loge ici trois lames de connexion 240 (voir figure 6), chaque lame de connexion 240 comportant une paire de contacts métalliques autodénudants 241 pour le raccordement d'un conducteur électrique 1, 2, 3 circulant dans le socle 11 de ladite goulotte 10, et au moins un contact métallique 242 destiné à venir en prise avec une des lames métalliques de connexion électrique 126A, 126B, 126C de l'appareillage électrique 100.Advantageously, this insulating cassette 210, 220 houses here three blades connection 240 (see FIG. 6), each connecting blade 240 having a pair of metal insulation contacts 241 for connection of a electrical conductor 1, 2, 3 flowing in the base 11 of said chute 10, and at least one metal contact 242 intended to engage one of the blades electrical connection wires 126A, 126B, 126C of the switchgear electrical 100.

Avantageusement, et comme le montre plus particulièrement la figure 6, chaque lame de connexion 240, logée dans ladite cassette isolante 210, 220, est agencée de sorte que la paire de contacts métalliques autodénudants 241 et ledit contact métallique 242 s'étendent selon deux directions Z, Y perpendiculaires.Advantageously, and as shown more particularly in FIG. 6, each connecting blade 240, housed in said insulating cassette 210, 220, is arranged so that the pair of metal insulation contacts 241 and said metal contact 242 extend in two directions Z, Y perpendicular.

Ici, chaque lame de connexion 240 comprend une paire de contacts métalliques 242 formant une pince allongée selon la direction Y, direction selon laquelle s'étendent les lames métalliques de connexion électrique de l'appareillage électrique 100, cette pince étant destinée à être enfichée sur une desdites lames métalliques de connexion électrique 126A, 126B, 126C dudit appareillage électrique 100.Here, each connection blade 240 includes a pair of contacts 242 forming an elongated clamp in the Y direction, direction according to which extend the metal blades of electrical connection of the electrical equipment 100, this clamp being intended to be plugged into a said metal electrical connection blades 126A, 126B, 126C of said electrical equipment 100.

Ici, pour chaque lame de connexion 240 logée dans ladite cassette isolante 210, 220, la paire de contacts métalliques autodénudants 241 est décalée latéralement par rapport à la paire de contacts métalliques 242 formant la pince.Here, for each connecting blade 240 housed in said cassette insulation 210, 220, the pair of insulation displacement metal contacts 241 is laterally offset from the pair of metal contacts 242 forming the clamp.

Bien entendu, selon une variante non représentée, on pourrait prévoir que la paire de contacts métalliques autodénudants et la paire de contacts métalliques de chaque lame de connexion soient alignées. Of course, according to a variant not shown, it could be provided that the pair of insulation displacement metal contacts and the pair of contacts metal of each connecting blade are aligned.

En outre, comme le montrent les figures 2 à 4, la cassette isolante comporte une base 210 et un couvercle 220 articulé sur cette base.In addition, as shown in FIGS. 2 to 4, the insulating cassette comprises a base 210 and a cover 220 hinged to this base.

Selon le mode de réalisation préférentiel représenté sur les figures, la base 210 et le couvercle 220 sont formés d'une seule pièce en matière plastique moulée et sont reliés l'un à l'autre par des parties souples formant charnières d'articulation 230.According to the preferred embodiment shown in the figures, the base 210 and cover 220 are formed of a single piece of plastics material molded and are connected to each other by flexible parts forming hinges articulation 230.

La base 210 de la cassette isolante porte en saillie, sur sa face interne, des clips 212 disposés selon trois rangées. Ces clips 212 forment des moyens de positionnement et de retenue des conducteurs électriques 1, 2, 3 destinés à être reliés via les lames de connexion 240 et aux lames métalliques de connexion électrique 126A, 126B, 126C issues des mécanismes de prise de courant 125 de l'appareillage électrique 100.The base 210 of the insulating cassette projects, on its internal face, clips 212 arranged in three rows. These clips 212 form means positioning and retaining the electrical conductors 1, 2, 3 for connected via the connecting blades 240 and to the metal blades of electrical connection 126A, 126B, 126C from the pickup mechanisms current 125 of the electrical equipment 100.

La face interne du couvercle 220 porte des moyens de positionnement et de retenue des lames de connexion 240 logées dans ladite cassette isolante du connecteur électrique 200.The inner face of the cover 220 carries positioning means and retaining the connecting blades 240 housed in said insulating cassette of the electrical connector 200.

Ces moyens de positionnement et de retenue comprennent des parois 222A, 222B faisant saillie de la face interne du couvercle 220 et définissant entre elles des logements pour, d'une part, les paires de contacts métalliques autodénudants 241, et, d'autre part, les contacts métalliques 242 en forme de pince desdites lames de connexion 240.These positioning and retaining means comprise walls 222A, 222B protruding from the inner face of the cover 220 and defining between they housing for, on the one hand, the pairs of metal contacts 241, and, on the other hand, the metallic contacts 242 in the form of clamping said connecting blades 240.

Bien entendu, ces agencements, formant moyens de positionnement et de retenue, viennent de formation respectivement avec la base 210 et le couvercle 220 de la cassette isolante.Of course, these arrangements, forming positioning means and of restraint, come from training respectively with the base 210 and the cover 220 of the insulating cassette.

Comme le montre plus particulièrement la figure 2, les lames de connexion 240 et les conducteurs électriques 1, 2, 3 sont positionnés et retenus respectivement sur le couvercle 220 et sur la base 210 de sorte qu'ils présentent alors des positions relatives telles que le montage du couvercle 220 sur la base 210 de la cassette isolante entraíne le positionnement des paires de contacts métalliques autodénudants 241 sur lesdits conducteurs électriques 1, 2, 3.As shown more particularly in Figure 2, the blades of connection 240 and the electrical conductors 1, 2, 3 are positioned and retained respectively on the cover 220 and the base 210 so that they present then relative positions such as mounting the lid 220 on the base 210 of the insulating cassette causes the positioning of the pairs of contacts metal insulation 241 on said electrical conductors 1, 2, 3.

Comme le montrent plus particulièrement les figures 3 et 4, avantageusement, le couvercle 220 de la cassette isolante comporte, sur sa face externe, des zones de pression 224 situées au droit des paires de contacts métalliques autodénudants 241 positionnées sur la face interne dudit couvercle 220.As shown more particularly in FIGS. 3 and 4, advantageously, the lid 220 of the insulating cassette has on its face external, pressure zones 224 located at the right of the pairs of contacts 241 self-cutting metal positioned on the inner face of said lid 220.

Ces zones de pression 224 sont ici des zones hachurées ou crantées indiquant à l'installateur, après fermeture du couvercle 220 sur la base 210 de la cassette isolante, l'endroit où il doit réaliser une pression à l'aide d'un outil, tel qu'une pince, pour provoquer l'enfichage desdites paires de contacts métalliques autodénudants 241 positionnées sur lesdits conducteurs électriques 1, 2, 3.These pressure zones 224 are here hatched or notched areas indicating to the installer, after closing the lid 220 on the base 210 of the insulating cassette, the place where he must apply pressure using a tool, such a clamp to cause the plugging of said pairs of metal contacts self-insulation 241 positioned on said electrical conductors 1, 2, 3.

Le couvercle 220 est relativement souple pour pouvoir se déformer élastiquement lors du pincement des zones de pression 224.The lid 220 is relatively flexible so as to be deformable elastically when pinching the pressure zones 224.

Par ailleurs, la base 210 de la cassette isolante porte, à proximité d'un de ses bords, deux dents d'encliquetage 211 destinées à venir s'encliqueter dans des ouvertures 221 prévues en correspondance sur le couvercle 220. Ainsi, on verrouille par encliquetage le couvercle 220 sur la base 210 de la cassette isolante.Furthermore, the base 210 of the insulating cassette carries, near a from its edges, two snapping teeth 211 intended to snap together in openings 221 provided in correspondence on the lid 220. Thus, the lid 220 is locked by snapping on the base 210 of the insulating cassette.

Sur les bords latéraux de la base 210 et du couvercle 220 de la cassette isolante, il est prévu des échancrures 223 qui, par complémentarité de forme lors de la fermeture du couvercle 220 sur la base 210, forment des orifices de passage des conducteurs électriques 1, 2, 3 (voir figure 3).On the lateral edges of the base 210 and the cover 220 of the cassette insulation, there are provided notches 223 which, by their complementary form when closing the lid 220 on the base 210, form openings passage of the electrical conductors 1, 2, 3 (see Figure 3).

Comme le montre plus particulièrement la figure 4, à l'arrière de la cassette isolante, il est prévu des ouvertures 216A, 216B, 216C débouchant chacune à l'entrée d'une pince de contacts métalliques 242 d'une lame de connexion 240 logée dans la cassette isolante.As shown more particularly in Figure 4, at the back of the insulating cassette 216A, 216B, 216C openings are provided each at the input of a metal contact clamp 242 of a blade of 240 connection housed in the insulating cassette.

Chaque lame métallique de connexion électrique 126A, 126B, 126C de l'appareillage électrique 100 est destinée à s'engager au travers d'une de ces ouvertures 216A, 216B, 216C pour son raccordement à une lame de connexion 240 du connecteur électrique 200, cette lame de connexion 240 étant elle-même raccordée à un conducteur électrique 1, 2, 3 passant au travers de la cassette isolante.Each metal electrical connection blade 126A, 126B, 126C the electrical equipment 100 is intended to engage through one of these openings 216A, 216B, 216C for connection to a connection blade 240 of the electrical connector 200, this connection blade 240 being itself connected to an electrical conductor 1, 2, 3 passing through the cassette insulating.

Ces ouvertures 216A, 216B, 216C, prévues à l'arrière de la cassette isolante sont, soit formées entièrement dans un rebord de la base 210, soit formées par complémentarité de forme entre la base 210 et le couvercle 220. These openings 216A, 216B, 216C, provided on the back of the cassette insulation are formed either entirely in a rim of the base 210 or formed by complementary form between the base 210 and the cover 220.

Avantageusement, le système électrique, représenté sur les figures, comporte des moyens de guidage et de centrage du connecteur électrique 200 sur l'appareillage électrique 100.Advantageously, the electrical system, shown in the figures, comprises means for guiding and centering the electrical connector 200 on electrical equipment 100.

Ici, ces moyens de guidage et de centrage comprennent, sur deux côtés latéraux opposés de la cassette isolante, deux nervures 213, et, sur les bords latéraux opposés de la surface supérieure 127A du socle 127 porté par le fond du boítier isolant de la partie arrière 120 de l'appareillage électrique 100, deux rainures 127B parallèles destinées à accueillir les deux nervures 213 de la cassette isolante positionnée sur la surface supérieure 127A dudit socle 127.Here, these guiding and centering means comprise, on two sides opposite sides of the insulating cassette, two ribs 213, and at the edges opposite sides of the upper surface 127A of the base 127 carried by the bottom of the insulating housing of the rear part 120 of the electrical equipment 100, two 127B parallel grooves to accommodate the two ribs 213 of the an insulating cassette positioned on the upper surface 127A of said base 127.

En outre, ces moyens de guidage et de centrage comprennent, selon le mode de réalisation préférentiel représenté, deux pattes de centrage 128 en matériau isolant s'étendant à partir des boítiers des mécanismes de prise de courant 125 de l'appareillage électrique 100 selon la direction Y, en direction de ladite ouverture latérale 123.In addition, these guiding and centering means comprise, according to the preferred embodiment shown, two centering tabs 128 in insulating material extending from the housings of the gripping mechanisms current 125 of the electrical equipment 100 in the direction Y, in the direction of said lateral opening 123.

En correspondance, il est prévu, à l'arrière de la cassette isolante formant le connecteur électrique 200, des ouvertures 218 accueillant lesdites pattes de centrage 128 lors du positionnement de la cassette isolante sur le socle 127.In correspondence, it is provided at the back of the insulating cassette forming the electrical connector 200, openings 218 accommodating said centering tabs 128 when positioning the insulating cassette on the base 127.

Au surplus, le système électrique comporte des moyens de verrouillage du connecteur électrique 200 sur l'appareillage électrique 100.In addition, the electrical system comprises locking means of the electrical connector 200 on the electrical equipment 100.

Ici, ces moyens de verrouillage sont des moyens d'encliquetage. Ces dits moyens d'encliquetage comprennent une dent d'encliquetage 129 prévue en saillie sur la surface supérieure 127A du socle 127 de l'appareillage électrique 100 et une encoche (non représentée) prévue en correspondance sur la face externe de la base 210 de ladite cassette isolante.Here, these locking means are latching means. These said detent means comprise a detent tooth 129 provided in projection on the upper surface 127A of the base 127 of the electrical equipment 100 and a notch (not shown) provided in correspondence on the face external of the base 210 of said insulating cassette.

Avantageusement, comme le montrent les figures 1 et 5, le boítier isolant de la partie arrière 120 de l'appareillage électrique 100 comporte, sur ses deux côtés latéraux parallèles, des adaptateurs 130 s'étendant au-delà de l'ouverture latérale 123 et aptes à se positionner contre une aile latérale 13 du socle 11 de la goulotte 10 pour adapter ledit appareillage électrique 100 à deux largeurs différentes de socle de goulotte, une petite largeur telle que représentée sur la figure 1, et une plus grande largeur non représentée. Advantageously, as shown in FIGS. 1 and 5, the insulating housing of the rear part 120 of the electrical equipment 100 comprises, on its two parallel lateral sides, adapters 130 extending beyond the opening 123 and able to be positioned against a lateral wing 13 of the base 11 of the chute 10 to adapt said electrical equipment 100 to two widths different trunking base, a small width as shown on the Figure 1, and a larger width not shown.

Pour l'adaptation de l'appareillage électrique 100 représenté à une plus grande largeur de goulotte, il suffit de détacher les adaptateurs 130 de la paroi périphérique 122 du boítier isolant par découpage de parties sécables.For the adaptation of the electrical equipment 100 represented to a more large chute width, simply detach the adapters 130 from the wall device 122 of the insulating housing by cutting breakable parts.

Ainsi, avec un même boítier isolant et une même partie avant 110 fonctionnelle, on peut adapter l'appareillage électrique 100 à deux largeurs différentes de goulotte.Thus, with the same insulating housing and the same part before 110 functional, we can adapt the electrical equipment 100 to two widths different chute.

Grâce au système électrique représenté sur les figures, l'installateur peut facilement raccorder électriquement le ou les mécanismes d'appareillage électrique de l'appareillage électrique 100 aux conducteurs électriques circulant dans un socle de goulotte.Thanks to the electrical system shown in the figures, the installer can easily connect the appliance mechanism (s) electrically electrical equipment 100 to electrical conductors circulating in a chute base.

Tout d'abord, il positionne, sur la face interne de la base 210 de la cassette isolante constituant le connecteur électrique 200, les conducteurs 1, 2, 3 en les coinçant entre les clips 212.First, it positions, on the inner face of the base 210 of the insulating cassette constituting the electrical connector 200, the conductors 1, 2, 3 by wedging them between clips 212.

Puis, il referme sur la base 210 le couvercle 220 portant sur sa face interne les lames de connexion 240, en le verrouillant par encliquetage dans les ouvertures 221 de ladite base 210.Then, it closes on the base 210 the cover 220 on its face internal connection blades 240, locking it by snapping into the openings 221 of said base 210.

Dans cette position, les paires de contacts métalliques autodénudants 241 des lames de connexion 240 sont positionnées sur les conducteurs électriques 1, 2, 3.In this position, the pairs of metal contacts self-removing 241 connecting blades 240 are positioned on the conductors electric 1, 2, 3.

Puis, en exerçant une pression, au moyen d'une pince par exemple, sur les zones de pression 224, ici des zones hachurées, il provoque l'enfichage des paires de contacts métalliques autodénudants 241 sur les conducteurs électriques 1, 2, 3 de façon à raccorder électriquement ces derniers aux lames de connexion 240.Then, exerting pressure, by means of forceps for example, on the pressure zones 224, here shaded areas, it causes the insertion of the pairs of 241 self-marking metal contacts on conductors 1, 2, 3 so as to electrically connect them to the blades connection 240.

L'installateur peut alors glisser la cassette isolante dans les rainures 127B bordant la surface supérieure 127A du socle 127 de l'appareillage électrique 100 de façon à engager les lames métalliques de connexion électrique 126A, 126B, 126C de l'appareillage électrique 100 au travers des ouvertures 216A, 216B, 216C du connecteur électrique 200 et à les enficher dans les pinces 242 des lames de connexion 240 dudit connecteur électrique 200. Lors de cette action, le connecteur électrique 200 est guidé sur le socle 127 par glissement des nervures 213 dans les rainures 127B. The installer can then slide the insulating cassette into the grooves 127B bordering the upper surface 127A of the base 127 of the apparatus electrical 100 so as to engage the electrical connection blades 126A, 126B, 126C of the electrical equipment 100 through the openings 216A, 216B, 216C of the electrical connector 200 and to plug them into the clamps 242 connecting blades 240 of said electrical connector 200. During this action, the electrical connector 200 is guided on the base 127 by sliding ribs 213 in the grooves 127B.

En bout de course, les pattes de centrage 128, s'engageant dans les ouvertures 218 correspondantes prévues à l'arrière du connecteur électrique, provoquent un centrage de ce dernier par rapport à l'appareillage électrique.At the end of the stroke, the centering tabs 128, engaging in the corresponding openings 218 provided on the back of the electrical connector, cause a centering of the latter with respect to the electrical equipment.

L'enfichage des lames métalliques de connexion électriques 126A, 126B, 126C dans les pinces 242 des lames de connexion 240 du connecteur électrique 200 s'effectue alors correctement.Plugging in the 126A electrical connection blades, 126B, 126C in the clamps 242 of the connecting blades 240 of the connector electrical 200 is then performed correctly.

En bout de course également, la dent d'encliquetage 129 de l'appareillage électrique 100 s'encliquette dans l'encoche correspondante de la cassette isolante de façon à verrouiller le connecteur électrique 200 sur l'appareillage électrique 100. Cet encliquetage provoque un signal sonore qui assure à l'installateur que le verrouillage est bien réalisé.Also at the end of the stroke, the ratchet tooth 129 of electrical equipment 100 snaps into the corresponding notch of the insulating cassette so as to lock the electrical connector 200 on electrical equipment 100. This snapping causes a sound signal that assures the installer that locking is done.

Dans cette position, telle que représentée sur la figure 5, les conducteurs électriques 1, 2, 3 circulant dans le socle 11 de la goulotte 10 sont très peu déviés par rapport à leur trajet initial.In this position, as shown in Figure 5, the drivers 1, 2, 3 flowing in the base 11 of the chute 10 are very few deviated from their original path.

Il ne reste plus à l'installateur qu'à fermer la partie arrière 120 de l'appareillage électrique 100 avec la partie avant 110 fonctionnelle qui recouvre le connecteur électrique 200 et la partie correspondante du socle 11 de la goulotte 10.It only remains for the installer to close the rear part 120 of the electrical equipment 100 with the functional front part 110 which covers the electrical connector 200 and the corresponding part of the base 11 of the chute 10.

La connexion électrique d'un tel système électrique aux conducteurs électriques du réseau est extrêmement simple, rapide et nécessite peu d'outil.The electrical connection of such an electrical system to the drivers Electrical network is extremely simple, fast and requires little tool.

La présente invention n'est nullement limitée au mode de réalisation décrit et représenté, mais l'homme du métier saura y apporter toute variante conforme à son esprit.The present invention is not limited to the embodiment described and shown, but the skilled person will be able to make any variant in keeping with his spirit.

En particulier, l'appareillage électrique du système électrique représenté pourrait être par exemple une simple prise de courant ou tout autre type d'appareillage électrique.In particular, the electrical equipment of the electrical system represented could be for example a simple socket or any other type electrical equipment.

En outre, on peut prévoir, selon une variante de réalisation de l'invention représentée sur la figure 8, que le connecteur électrique 200' comprend une cassette isolante 210', 220' à rapporter également dans une ouverture latérale de la partie arrière d'un appareillage électrique, au-dessus du socle de la goulotte. Cette cassette isolante 210', 220' loge également trois lames de connexion 240 qui comprennent chacune une paire de contacts métalliques autodénudants 241 pour le raccordement d'un conducteur électrique 1, 2, 3 circulant dans le socle de la goulotte et au moins un contact métallique 242 destiné à venir en prise avec une des lames métalliques de connexion électrique de l'appareillage électrique concerné.In addition, provision may be made according to an alternative embodiment of the invention shown in FIG. 8, that the electrical connector 200 'comprises a insulating cassette 210 ', 220' to be reported also in a side opening the rear part of an electrical equipment, above the base of the chute. This insulating cassette 210 ', 220' also houses three blades of connection 240 which each include a pair of metal contacts self-bending 241 for connecting an electrical conductor 1, 2, 3 flowing in the base of the chute and at least one metal contact 242 intended to engage with one of the metal blades of electrical connection of the electrical equipment concerned.

Tout comme les lames de connexion 240 représentées sur la figure 6, celles représentées sur la figure 8 sont agencées de sorte que la paire de contacts métalliques autodénudants 241 et le contact métallique 242 s'étendent dans deux directions perpendiculaires.Like the connecting blades 240 shown in FIG. 6, those shown in Figure 8 are arranged so that the pair of insulation displacement metal contacts 241 and metal contact 242 extend in two perpendicular directions.

Chaque lame de connexion 240 comprend également une paire de contacts métalliques 242 formant une pince allongée selon la direction selon laquelle s'étendent les lames métalliques de connexion électrique de l'appareillage électrique concerné, cette pince étant destinée à être enfichée sur une desdites lames métalliques de connexion électrique dudit appareillage électrique.Each connection blade 240 also includes a pair of metal contacts 242 forming an elongated clamp according to the direction according to which extend the metal blades of electrical connection of the electrical equipment concerned, this clamp being intended to be plugged into one of said metal blades for electrical connection of said apparatus electric.

Comme le montre la figure 8, selon cette variante de réalisation, la cassette isolante comporte une base 210' et un couvercle 220' articulé sur cette base par l'intermédiaire d'une languette souple 225' formant charnière d'articulation.As shown in FIG. 8, according to this variant embodiment, the insulating cassette comprises a base 210 'and a cover 220' articulated on this base via a flexible tab 225 'forming a hinge hinge.

La base 210' et le couvercle 220' sont formés d'une seule pièce en matière plastique moulée et sont reliés l'un à l'autre par ladite languette souple 225'.The base 210 'and the cover 220' are formed in one piece from molded plastic material and are connected to each other by said flexible tongue 225 '.

Ici, la base 210' de la cassette isolante présente, sur sa face interne, une pluralité de logements 211', 212', 213' distincts, disposés en quinconce, chaque logement 211', 212', 213' accueillant un conducteur électrique 1, 3, 2 de telle manière que chacun de ces conducteurs électriques est retenu dans le logement correspondant de la base 210'. Le couvercle 220' comporte une pluralité de parties 221', 222', 223' distinctes destinées à fermer chacun desdits logements 211', 212', 213' distincts de la base 210'. Chaque partie 221', 222', 223' du couvercle 220' porte, sur sa face interne, des moyens de positionnement et de retenue d'une lame de connexion 240. Les parties 221', 222', 223' distinctes du couvercle 220' sont reliées entre elles par des languettes 224' souples de sorte que la fermeture de chaque logement de la base 210' par chaque partie du couvercle 220' se fait de manière indépendante de la fermeture des autres logements de ladite base. Here, the base 210 'of the insulating cassette has, on its internal face, a plurality of separate housings 211 ', 212', 213 'arranged in staggered rows, each housing 211 ', 212', 213 'accommodating an electrical conductor 1, 3, 2 of such way that each of these electrical conductors is retained in the housing corresponding of the base 210 '. The lid 220 'has a plurality of separate parts 221 ', 222', 223 'intended to close each of said dwellings 211 ', 212', 213 'separate from the base 210'. Each part 221 ', 222', 223 'of cover 220 'carries on its internal face, positioning means and retaining a connecting blade 240. The parts 221 ', 222', 223 'distinct from the cover 220 'are interconnected by tongues 224' flexible so that the closure of each housing of the base 210 'by each part of the lid 220 'is done independently of the closure of others housing of said base.

En outre, on remarquera que chacune des parties 221', 222', 223' distinctes du couvercle 220' comporte une dent 226' d'accrochage sur une dent complémentaire 216' prévue sur la face interne de la base 210'.In addition, it will be noted that each of the parts 221 ', 222', 223 ' separate from the cover 220 'has a tooth 226' hooking on a tooth complementary 216 'provided on the inner face of the base 210'.

Avantageusement, cette variante du connecteur électrique selon l'invention permet à l'installateur d'éviter, lors de la connexion d'une paire de contacts métalliques autodénudants 241 d'une lame de connexion 240 sur un conducteur électrique 1, 2, 3 logé dans un des logements 211', 212', 213' de la base 210', de provoquer la déconnexion des autres paires de contacts métalliques autodénduants 241 des autres conducteurs électriques 1, 2, 3. En fait, selon cette variante, chaque connexion électrique est individualisée au sein de la cassette isolante 210', 220' elle-même.Advantageously, this variant of the electrical connector according to the invention allows the installer to avoid, when connecting a pair of insulation displacement metal contacts 241 of a connection blade 240 on a electrical conductor 1, 2, 3 housed in one of the housings 211 ', 212', 213 'of the base 210 ', to cause the disconnection of the other pairs of contacts 241 of the other electrical conductors 1, 2, 3. fact, according to this variant, each electrical connection is individualized within of the insulating cassette 210 ', 220' itself.
